  • Synthesis gas manufacture
    Patent number: 3968052
    Abstract: Synthesis gas is prepared by contacting coal-derived char particles with steam in a fluid-bed gasifier wherein heat for the endothermic reaction is supplied by passing through the gasifier a stream of inert pellets heated externally of the gasifier. The pellets, after leaving the gasifier, are separated from entrained char, and then conveyed into a heater where the fines from the external cyclone of the gasifier are burned in the presence of the circulating pellets to produce the heat necessary for the reaction.
